Distylium plant named ‘PIIDIST-II’

ABSTRACT

A new and distinct cultivar of  Distylium  plant named ‘PIIDIST-II’, characterized by its compact, spreading growth habit, maroon-purple new growth, dark blue-green mature foliage, and reddish maroon flowers.

Genus and species of plant claimed: Distylium sp. hybrid.

Variety denomination: ‘PIIDIST-II’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Distylium plant, botanically known as Distylium sp. hybrid, a member of the Hamamelidaceae, and hereinafter referred to by the cultivar name ‘PIIDIST-II’.

‘PIIDIST-II’ originated as an open-pollinated seedling from seed collected from a Distylium sp. hybrid (Distylium myricoides×D. racemosum) growing in Watkinsville, Ga. ‘PIIDIST-II’ was selected in the summer of 2006 by the inventor in a cultivated environment in Dearing, Ga.

Asexual reproduction of ‘PIIDIST-II’ by stem cuttings, performed in Watkinsville, Ga., since 2006 has shown that all the unique features of ‘PIIDIST-II’, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘PIIDIST-II’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PIIDIST-II’. These characteristics in combination distinguish ‘PIIDIST-II’ as a new and distinct cultivar: 1. Compact, spreading growth habit; 2. Maroon-purple new growth; 3. Dark blue-green mature foliage; and 4. Reddish maroon flowers.

Plants of ‘PIIDIST-II’ differ from plants of the parent, Distylium sp. hybrid, primarily in growth habit, foliage color, and cold hardiness, as plants of ‘PIIDIST-II’ have a compact, spreading growth habit, maroon-purple new growth, dark blue-green mature foliage, and increased cold hardiness, whereas plants of the parent have an upright, spreading growth habit, medium green mature foliage, and are less cold hardy.

Plants of the new Distylium ‘PIIDIST-II’ can be compared to plants of the cultivar ‘PIIDIST-I’ (U.S. Plant patent application Ser. No. 13/068,262), which is a sibling that originated from the same open-pollination. ‘PIIDIST-II’ has a compact, spreading growth habit, maroon-purple new growth, dark blue-green mature foliage, and reddish maroon flowers, whereas ‘PIIDIST-I’ has a compact, upright-spreading growth habit, yellow-green new growth, dark green mature foliage, and reddish purple flowers.

Plants of the new Distylium ‘PIIDIST-II’ can be compared to plants of the cultivar ‘Vintage Jade’ (U.S. Plant Pat. No. 23,128), which is a sibling that originated from the same open-pollination. ‘PIIDIST-II’ has a compact, spreading growth habit, maroon-purple new growth, dark blue-green mature foliage, and reddish maroon flowers, whereas ‘Vintage Jade’ has a compact, layered, mounding and spreading growth habit, light green new growth, dark green mature foliage, and reddish maroon flowers.
